I keep gettin these letters also, I hadn't filed in like 9 years, but last year I got caught up and didn't owe a thing, now I'm getting them again and they have my new address, this is how they sent me my check last year, who knows, wish Huckabee would have won, so he could have shut these nazi's down. Hope this helps.
